A 3D XFEM instead of a quasi-3D XFEM can model the sloping matrix cracks that occurred in QSI experiments, but further development is required. For the OHT test analyses, a zig-zag CZM is required for … Witryna10 kwi 2015 · The XFEM was initially proposed to tackle the strong-discontinuity problem in relation to crack growth and was soon extended to other problems characterized by localization, complex geometries and multi-phase. The method has two main advantages over other numerical methods.
